CRC_{mean,max,peak} product versus RMSD box plot. Each of the 600 pairs of image reconstructions parameters combinations is represented by a box (top row). The color scale from blue to red represents the different level of overall filtration. Dark blue boxes represent combinations with least overall filtration (i.e., 3 mm for both mMR and Signa images), and dark red corresponds to most filtration (7 mm on mMR and Signa images). Bottom row, expanded view at low RMSD to identify candidate image reconstruction parameters for optimization. The solution for best RMSD and CRC is indicated in green
